The Adusta RSJ crankbait is a combination of extremely long casts and strong body action. The concept of long casting and strong body action has been retained in this wobbler, just like in the other ADUSTA models. It is an ideal lure for anglers fishing from the bank, who can fish further parts of the water inaccessible with other lures. The flattened body ensures a strong action of the lure even when retrieved slowly. When twitching or jerking, the RSJ makes a natural retrieve that predators cannot ignore. This design ensures that the ADUSTA RSJ can be used to catch fish in flowing and standing waters. The lure can, of course, be used in all conditions and can be guided using many spinning or casting techniques.

To ensure accurate and extreme long casts, the lure contains extremely precisely balanced tungsten balls (rattle), which provide a moving centre of gravity to increase the range of the fished water zone.
